Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a catheter set.
Background
Acute urinary retention is one of the common diseases in emergency treatment of urinary surgery, the main causes of the acute urinary retention include benign prostatic hyperplasia, bladder neck contracture, urethral stricture, bladder outlet obstruction caused by urethral trauma and the like or the damage of urethral integrity, and an emergency treatment indwelling catheter is usually needed.
However, a considerable number of patients in clinical practice have difficulty in catheterization, and the patients need to replace the hard catheter for many attempts or perform urethral dilatation and then insert the catheter, thereby suffering from the pain caused by many catheterization operations. And consequently severe hematuria, and even infection, occurs. Even after urethral dilation is performed on some patients, the catheter cannot be successfully placed, mainly because the urethral dilator cannot enter the bladder, or after the urethral dilator is inserted and pulled out, the urethral is retracted and the catheter cannot be placed because the toughness of the catheter is obviously lower than that of the urethral dilator or other reasons. For the patients who can not smoothly put the catheter, the operation with larger wound such as cystoscope urinary catheter putting operation or suprapubic cystostomy operation is needed, and the pain, hematuria, infection and other risks of the patients are obviously increased.
There are related patents which propose solutions for following the urethra dilated by the urethral dilator with a guide wire and guiding the subsequent catheter to avoid the above problems as much as possible. This type of catheter usually has a dilator and a catheter opening at the very front end of the tubular housing, whereas the minimum size of a urethral dilator is 8F, i.e. an outer diameter of only phi 0.264 cm. Limited by the extremely fine outer diameter and hollow structure of the catheter, the dilator and the catheter are further sharp due to the difficulty in chamfering the front end, and the delicate urethra is easily damaged in the catheterization operation. Therefore, it is necessary to optimize the structure further to reduce the pain of the patient caused by inserting the catheter.
